Display Layout Toolkit

A Linux X11 alternative to Actual Multiple Monitors.
Disclaimer: Independent open-source project, not affiliated with or endorsed by Actual Tools.
Multi-monitor arrangement and cursor confinement require an X11 session; Wayland-native
compositors do not allow third-party RandR layout changes or pointer grabs.

FEATURES
• Visual drag-and-drop monitor arrangement & RandR output editor: inspect real RandR outputs,
resolutions, refresh rates, scales and rotation, drag displays on a proportional canvas with
edge snapping, preview the generated xrandr command, and apply with a 15-second auto-revert
confirmation dialog or save/apply JSON layout presets.
• Pointer monitor confinement & edge resistance: confine the X11 cursor inside any monitor via
XGrabPointer (InputOnly confine window), XFixes pointer barriers, or XWarpPointer soft
clamping with adjustable inter-monitor edge resistance and live cursor telemetry map.
• Per-monitor dimmer & blackout overlays: dim or black out individual monitors (0%-100%
opacity, custom tint, optional click-through or ESC/click-to-restore) for focus or video.
